G3 dropout options

I am currently running a QR on the back of my Uzzi, but would like change this out for something a little stiffer. I have a Hope rear hub so can change out the axle, and if at all possible I would like to lose the stupid fiddly end spacers that fit into the outside of the dropouts.

Do I have to go to 12mm to get rid of the spacers? If so are there any good 12mm systems anyone can recommend?

If I go with 10mm (probably DT Swiss RWS) will I need new spacers or will they use the same ones as the QR setup I have now? I got the frame second hand so currently only have the one set of spacers.

Not fully sure if I'll make it to Bellflower. I haven't been riding at all, so my bike handling skills aren't what they should. I'll bring the Mob and maybe the Intense Podium.

I'm assuming the G3 dropouts are the similar in how the axle mounts as the dropouts on the M6/SlopeStyle/Socom/etc, in which case you can use the fun bolts without any adapter. The head of the bolt fits perfectly into the dropout.

Here's my SlopeStyle.

Yeah they're the same, thats what I've been using for the last year with no problems on my Uzzi.

So, I don't get it...
The part of the fun bolt that slides into the frame is supposed to be 10mm so that it works with conventional QR slots, yet the G3 dropout slot has to be 12mm to accomodate the 12mm axle... so what's up with the missing 2mm? No spacers being used?

I hesitate to even question y'all (esp since I know Lee and am quite certain he's got major mechanical skills)... but are y'all sure that the shaft of the funbolt, and not the bolt head, is carrying the load of the axle?

OK, I'm gonna have to ride home for lunch and get the FunBolts back out of the bag and see how it'll fit in there...

I dunno fellers. If y'all's G3 dropouts are like mine, you'll see that the Funbolt head fits perfectly in the circular milled out part of the dropout, but the Funbolt shaft is not bottomed out in dropout.

I took off my rear wheel and just set the Funbolt in the dropout, and the Funbolt shaft is suspended in midair when the bolt head is seated. There is basically that 1mm gap all the way around the 10mm funbolt shaft in the 12mm dropout slot.

I'm guessing the clamping force between the hub and the frame takes most of the load, but it seems it might put undo stress on the junction between the funbolt shaft and head, which could lead to a snapped bolt. For me, I'm not sure I'd be comfortable riding on that setup.

Y'all please check for me to see if your setup has this "feature" so that I can sleep tonite!

Thats how it works, I've been running like that for a year so far with no problems. It's not much different with the QR/10mm dropout spacers and a QR/10mm setup other than there's something filling the gap on the top of the bolt. The area taking the stress is still the head of the spacer and the hub, it isn't like there's anything touching the bottom of the QR/10mm spacer to hold it in place.

Check your dropouts! On my Uzzi they did not chamfer the inside of the counter bore on the drop outs where the adapter sits. There is a small radius (tool nose radius from the insert used to machine the adapter) in the corner of the 10mm-12mm adapter. This means that when you clamp down on a 10mm axle or QR the tool nose rad on the adapter contacts the sharp corner on the dropouts. You do not get contact on the flat surfaces. Ditch the 10mm stuff and only run 12mm axle with a nut on one end and a washer underneath the head on the other. I suspect a lot of people running 10mm axle who complained about flex in the rear end were suffering because of the goofy adapters. Sorry if this seems a little bit out there but as a machinist I notice small things like this as it is the difference between an ok part and a perfect part. On a different note I have noticed that the quality of the machining has increased in the time between when they made my wife's 09 SS1 and my 11 Uzzi.
